If your opponent controls a monster and you control no monsters, you can Special Summon this card (from your hand) by discarding 1 other card. When this card destroys a monster by battle: You can pay 1000 Life Points; add 1 "Patchwork Numeron" from your Deck to your hand.

good ATK + no protection is just a beater in what i'm guessing in a relentless beatdown deck, right? this hit's the field gets destroyed, pay lp to get another one, which means you really do have to keep up with your hand. Since it's not saying during either player's turn, it's slow enough for your opponent to think of how to deal with the 2nd and/or 3rd. is there a deck based around them? that effect is very good, but not OP in my opinion, but the right protection, searchers and added support could put a great deal of pressure on your opponent, which is what you'd want to do anyway in this game lol
